Dynamic fracture of explosion containment vessels subjected to internal blast loads is the foundation for conducting safety assessment and failure analysis of explosion containment vessels. The experiments were carried out to investigate dynamic fracture characteristics of cylindrical steel shells subjected to internal blast loadings at the centers. The elastic-plastic response of cylindrical steel shells was conducted using nonlinear dynamic finite element analysis code LS-DYNA. The fracture mode and fracture mechanism of a cylindrical shell were specially studied through analysis of deformation， macrographs of fracture surface and elastic-plastic response. The results show that dynamical ductility deformations appear and the shear bands form when the cylindrical steel shell expands under internal blast loading. The cylindrical steel shell fractures preferentially along the shear bands due to its softening effect. The fracture mechanism is that the shear bands tear under tensile circumferential stress. The shear bands and the tensile circumferential stress dominate the final fracture mode. The fracture mode is of the ductile fracture.

Broken rules of cylindrical steel shell subjected to internal blast loads is the foundation for conducting safety assessment and failure analysis of explosion containment vessels. The experiments were carried out broken rules of the cylindrical steel shells subjected to internal blast loadings at the centers. The elastic-plastic response of cylindrical steel shells was conducted using nonlinear dynamic finite element analysis code LS-DYNA. The results show that the deformation was’t a discrepancy in the explosion center of the cylindrical steel shell in same space, and the deformation descended slower along with thickness augmentation in the end of explosion center. The radial stress、hoop stress and axial stress was a discrepancy in the thickness way of cylindrical steel shell of explosion center The most leading cause of destructivity of cylindrical steel shell was that inner wall bearing normal stress and exterior wall bearing tensile stress; the hoop stress was broken more than axial stress cylindrical steel shell. The whole process was presenting hoop fractured and axial growth.

Resistance strain gauge is common used in strain measurement, particularly in small elastic strain measurement, it has many advantages. However when the measured strain increases, the output nonlinearity of the Wheatstone bridge will become obvious; in this paper the nonlinearity error of the output in large-strain measurement is analyzed, and based on this a mathematical algorithm for nonlinearity compensation is proposed; finally the effect of the algorithm for nonlinearity compensation is proved by theoretical research and experimental treatment.

The Key of Web Services lies in how to describe and find Web serve, and which is mainly realized depending on UDDI technology is realized. The company which provided the services by UDDI can register information, it can make the potential user and/or cooperative partner find the services and simple shelf of the business of these companies. At the same time, UDDI can make company find other company, so as to expand the potential business partnership. We can say UDDI has offered the chance for company to step into new market and service, also make the companies in all scales expand their own place business among the global market rapidly.

With the rapid development of the Internet and information, communication technology, human society began to enter into the intelligence community with the digital and network platform. With the popularization of computer application in schools, enterprises and other institutions, the meetings of governments, enterprises and institutions has broken the traditional model that the meetings are held in the same place and at the same time, and network meetings is to be popularized with the increasingly fast paces. But regardless of the company or the university, there exists the problems of meeting management. Now the overwhelming majority of the conference management is still in a state of manual, inefficient and prone to error, not manageable, not rule out any untrue phenomenon. Therefore, the internal management, self-improvement of the meeting management can not be ignored. This paper aims to resolve this problem by designing a meeting management website. Conference Management website ASP can be used to design the conference management website, ASP (Active Server Pages) dynamic website is a technology which is introduced by Microsoft Company to replace CGI (Common Gateway Interface)-a common Gateway Interface. By combining the knowledge of ASP HTML language, ASP directives and ActiveX components and Access database, the paper uses the own Web server to create and run a dynamic interactive Website 。The paper aims to realize the work of meeting managing, application, auditing, controlling, minutes of meetings processing through the meeting management website.
